Parallelize Large-Scale Code Migrations Using /fork Background Agents
Scale your productivity by running multiple coding agents in parallel.
Initiate the /fork command to backgrounds agents for parallel task execution, managed through a central visual panel.
The Scenario
You need to perform a repetitive task across multiple different directories or modules, such as updating API calls or changing styling patterns across a large repository.
Before & after
Developers handle large-scale migrations by processing one file or module at a time in a linear fashion, taking several hours for large projects.
Run the /fork command to spin up multiple agents that work in parallel from a central panel, cutting total execution time to 5–10 minutes.
The Prompt
/fork [TASK_FOR_NEW_AGENT_E.G._UPGRADE_UI_COMPONENTS_TO_VERSION_2]
The /fork command allows you to spawn background agents to handle different parts of a codebase simultaneously. With the new parallel agent panel, you can monitor and manage these threads using keyboard navigation.
